Police arrested a former armyman on Monday night on charge of killing his teenaged daughter at Rewari Khera village in Bhiwani district.
The 16-year-old girl was shot dead by her father Ratanpal in an inebriated condition, the police said.
The family reportedly quietly cremated the body after the crime. A forensic team was sent to the cremation site on Tuesday for collecting samples, superintendent of police (SP) B Satish Balan said.
Police authorities meanwhile suspended village police station incharge assistant sub-inspector for not reacting in time and allowing the body to be cremated.
The SP said it was not a case of "honour killing", adding that a case under Section 302 of IPC had been registered.
